Data offered docs-verified: life cycle inventory (LCI) computation · life cycle impact assessment (LCIA) scores · supply chain dependency trees · contribution analysis by flow and activity · method characterization factor mapping to database flows · LCIA normalization and weighting
Coverage llm-inferred: Global
Formats docs-verified: EcoSpold2 (.spold) · EcoSpold1 (.xml) · SimaPro CSV · ILCD process datasets · openLCA JSON-LD (zip) · Brightway Excel (.xlsx) · SimaPro method CSV · CSV · ILCD method package (zip)
Access llm-inferred: Apache-2.0 open-source licence (per ENTRY); optional single-code password login on the server, set via VOLCA_PASSWORD (per ENTRY)

Use cases llm-inferred: Embodied carbon and impact comparison of alternative civils materials (e.g. concrete, steel, pipe options) using an LCA database loaded into VoLCA · Contribution analysis to identify the dominant flows driving a drainage or water-infrastructure scheme's impact score · Checking how well a method collection's characterization factors map onto the flows in a loaded database before running impact assessments · Supply chain tracing of upstream suppliers for a product used in an environmental consultancy LCA
Audience llm-inferred: LCA practitioners · environmental consultants · sustainability analysts · civils and BIM engineers working on embodied carbon

Constraints docs-verified: Runs in memory against the user's own LCA databases; no database is bundled · Process memory is two to three times the size of the loaded database, so peak memory must be provisioned accordingly · First load and first computation after load are slow (tens of seconds and seconds respectively)
